UNDERSINK BOILING WATER
Note:
Ventilation Buffers
Included in the installation pack are adhesive backed silicon buffers. If air vents are not installed in
the cupboards housing the Birko unit, the buffers must be placed on the inside edge of the cupboard
door to create a slight gap ensuring a minimum airflow. Failure to do this may cause the Birko unit to
overheat and operate inefficiently.
Water Supply
The system is designed to be connected to a cold water supply via
1) a filter (provided),
2) a pressure limiting valve (not provided) and
3) an isolating valve (not provided).
Never connect this system to a hot water or warm water supply.
Minimum operating pressure is 200 kPa and maximum of 800 kPa.
Cold water supply temperature should range only from 5°C to 30°C.
Do not use sealing paste on water supply joints as it may taint water.
Plumbing
Do not remove the cover of the under-sink unit during installation.
All connections can be accessed from the top of the unit without removing the cover.
To install the tap, first cut a 22 mm diameter hole in the sink.
Position the tap so the spout drains directly into the sink.
For safe operation, position tap button at right angles to spout.
Pass the tap hose and cable through hole to under-sink unit.
Clamp tap base in position using plastic nut and washer provided.
Install the safe tray (provided) in the cupboard beneath the tap.
Place the under-sink unit in position within the safe tray.
Trim the tap hose to length and fit to the under-sink unit outlet.
Do not coil, kink or extend the tap hose connected to the outlet.
Connect the low voltage cable from the tap to the under-sink unit.
Do not cut the cable: excess cable must be coiled and tied off.
